Its the same size as the oem teflon hose in the pump assembly. I used a paxton add-a-pump kit that came with the fuel pumps when i bought them.

Back in the car i used the install directions from turbosmarts website to wire it up. Needed a 12v key on and ground which i had there easily from my switches, also wired it so i can turn it on off with the switch for the wideband gauge as well. Also needed a rpm signal, Since i already had the raptor shiftlight installed i just spliced off of the rpm signal wire right there at the raptor. Then its just running the other 2 wires to the engine bay that will go to the solenoid, and the vac line.
Some pics installed
To make it easy i just routed the wires and vac line behind the door trim insulation below the a-pillar and into the engine bay. Left the wires fro now till i find a good spot to mount the solenoid and hooked up the vac line to the vac hose going to the fuel rail sensor.
All patched up!
